Depression era Vitrock Anchor Hocking milk glass mixing bowls, 8 1/2", 10 ¼1/4" and 11 1/4" across the grip rims. The larger two are marked VITROCK, the smallest is unmarked and of a slightly different pattern, though works pretty well in this set.
None of the three bowls have chips or cracks, though all have wear and scratching from use (the smallest bowl is the most worn). These opaque milk glass mixing bowls are hard to find these days. I use my own Vitrock bowls every day, these are my absolute favorite in the kitchen, out in the garden, on the table!
